摘要 雷电对于变电站综合自动化设备的安全与稳定运行危害极大,充分认识雷电损伤效应及其传播途径对变电站综合自动化设备防雷意义重大。文中详细分析了雷电的静电感应和电磁感应造成损伤的原理,给出了相应的防雷器件的选型和防雷模块的设计方案,并依照实际使用经验给出了其它一些防雷措施以供提升变电站自动化设备通讯接口整体的防雷水平。 Lightning does great harm to the secure and reliable operation of automatic devices in substations. It's very important for lightning protection to understand the mechanism of lightning damage and its infiltrating way. This paper analyzes the damage mechanism of static induction and Lightning Electro Magnetic Pulse, and then gives the design schemes of SPD for lightning protection. According to practical experience, some auxiliary schemes are given for increasing lightning protection level of automatic devices within substations.
